VVProPrepa: the reactor building in one click

The Grand Carénage programme involves an increase in the maintenance work on French nuclear power plants. The challenge for the EDF Group is therefore optimising work on-site during shutdowns, especially in the reactor building. To effectively train the maintenance teams, EDF’s R&D division has developed VVProPrepa, a digital innovation that uses video gaming technologies and allows users to explore reactor buildings down to the smallest detail.

Highly detailed knowledge of each building is central to preparing all maintenance projects. In line with EDF’s digital ambitions, VVProPrepa makes this knowledge available using virtual reality techniques. The result is a valuable increase in performance by reducing the length of shutdown periods. Operating reactor buildings’ non-accessibility, a major maintenance constraint, has now been removed. From now on, operators can easily use VVProPrepa and its comprehensive visual data: a choice of navigation methods, unique viewpoints of the reactor building that give a clearer understanding of its structure, the ability to measure distances, add comments, calculate routes... and more. Nuclear specialists can now explore work areas at any time, especially during the crucial preparatory phase.
